marine wildlife and many different kinds of building materials (eg. Limestone and marble will get eroded by acid rain). Note: Every drop of “1” in pH level increases the acidity by 100x. The main acids that get released into the air are: multiple sulfur oxides (SOx), which are also released by volcanoes; and nitric oxides (NOx), which are also released into the

precipitation, which is unusually acidic according to the pH scale (the scale numbered from 0 to 14 to measure acid levels in pH), dry deposition refers to an accumulation of acidic gases and acidic particles. Most of the release of chemicals such as sulfur dioxide and nitrogen oxides by

surface area is typically 300 to 500 m2/kg, although some fly ashes can have surface areas as low as 200 m2/kg and as high as 700 m2/kg. Fly ash is primarily silicate glass containing silica, alumina, iron, and calcium. Minor constituents are magnesium, sulfur, sodium, potassium, and carbon. Crystalline compounds are present in small amounts. The relative density (specific gravity) of fly ash generally ranges between 1.9 and 2.8 and the color is generally gray or tan. ASTM C 618 (AASHTO M 295) Class F and

Sulfur dioxide (SO2) is a colorless gas with an irritating odor that cannot be seen or tasted. It is considered as one of the air criteria pollutants along with carbon monoxide, particulate matter, ground-level ozone, lead, and nitrogen dioxide by the Environmental Protection Agency (EPA). SO2 belongs to a group of highly reactive gases called sulfur oxides (SOx) which reacts easily with other substances to form harmful compounds, such as sulfuric acid, sulfurous acid, and sulfate particles.

1. Introduction Industrial emissions are a major sources of air pollution, and thus responsible for numerous deleterious effects on a human health and environment caused by photochemical smog, acid rain, and resultant degradation of ecosystems and bio-diversity. Ontario’s SO2 emissions are predominantly around 65 percent from industrial sources including non-ferrous smelting. The major environmental concerns associated with smelting are “energy consumption, releases of sulphur dioxide and particulate

During and since World War II the United States has produced millions of tons of toxic wastes during the manufacturing and processing of products. These hazards were often left abandoned and no one really paid attention to their effect on our environment. In the 1980s Congress established a Superfund Program. It was left for the Environmental Protection Agency (EPA) to administer the superfund program, to find these hazardous sites, investigate and determine the worst ones, and then clean up those

In order to power the industrial age, humans have burned gigantic amounts of coal to produce any form of power. Coal naturally contains high amounts of sulphur and burning of coal produces huge amounts of heat and the sulphur present in the coal combines with the atmospheric oxygen to produce Sulphur Dioxide. The smoke stacks of a power plant throw out all the waste gases into the atmosphere which contains huge amounts of Sulphur Dioxide. It is said that thermal power plants are the largest contributor

Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain, snow, or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog, or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world, such as above the tropical rain forest of Africa. Acid rain

rain forms in the atmosphere from chemicals created by the burning of fossil fuels. When coal and oil are burned they release sulfur dioxide (SO2) and two nitric oxides, nitric oxide (NO) and nitrogen dioxide (NO2) designated by the symbol NOX. These dangerous chemicals come from the smoke that pours from factory chimneys and exhaust from car tail pipes. Once released, sulfur dioxide and nitrogen oxides react with other chemicals in the air, water

PbO2 + Pb + 2H2SO4 ↔ 2PbSO4 + 2H2O The reaction of lead and lead oxide with the sulfuric acid electrolyte produces a voltage. The supplying of energy to and external resistance the battery. When a lead acid battery cell produces energy, it converts chemical energy into electrical energy. During this process, Lead is oxidised at the anode according to this equation: Pb(s) → Pb2+(aq) + 2e- The reduction process in lead acid batteries occurs at the cathode, as shown above. Lead (from lead dioxide) is
